Broken Links in Optimizers Documentation

[asukakenji]

There are typos in the following links, the subdirectory should spell optimizers instead of optimizer:

keras-io/templates/api/optimizers/index.md

Line 65 in 01f488d

You can use a [learning rate schedule](/api/optimizer/learning_rate_schedules) to modulate

keras-io/templates/api/optimizers/index.md

Line 76 in 01f488d

Check out [the learning rate schedule API documentation](/api/optimizer/learning_rate_schedules) for a list of available schedules.
